Duplicate [suggestion] @ Mentioning

i got the idea from the facebook newsfeed, cause i really like that kind of feature.

When i'm answering in a thread where Kier and some other (less important ) guys had posted and i'm writing an @ followed by the letter K, a list is popping up with all (or maybe just 3 ordered by count of answers in that thread) the users who has replied in that thread.
The user who was mentioned get's an alert.

Would be awesome if you could build in that feature.

User tagging and thread tagging are great social features which really bring the community and the content closer to the community. I really am loving how DBTECH did this for vbulletin, so hopefully they or XF will do this as a mod for here when the time comes (I think too much stuff added default may just be bloat tho).
